"The findings have implications for public health care policy. First, they add to evidence that bouts of unsoothable crying, which are common in early infancy, are not much affected by variations in parenting, providing reassurance that this aspect of infant crying is not parents' fault. Second, the findings provide information that professionals can give to parents to help them to make choices about infant care. Third, the findings support some experts' concerns that many English parents are adopting methods of care that lead to increased crying in their infants."article from PEDIATRICS Vol. 117 No. 6 June 2006
